To add fractions we have to find a common denominator and then add. To find the common denominator of the fractions we can multiply the denominators together to get 40.

Multiply 5/8 × 5/5 = 25/40
Multiply 2/5 × 8/8 = 16/40

Now add the fractions

25/40 + 16/40 = 41/40 or 1 1/40

Well you would have to make the bottom number equal, so the lcm (least common multiple) of 5 and 8 is 40. Which means for the first you have to multiply 5 and 8 both by five to get 25/40. Then multiply 2 and 5 both by 8 so 16/40 then add. So 25/40 + 16/40 = 41/40.

So the answer is 41/40, which reduced ia 1 and 1/40.

Hope that helps!

Use the expression 4^{3}+8-\dfrac9y4
muminat
So first you would evaluate the power making the 4^3=64 then keep the rest of the problem the same.... then add the numbers 64+8 since their the whole numbers and that would equal 72 so now the problem should be 72-9/y. After that you write all the numerators above the common denominator making the final answer to be 72y-9/y

iVinArrow [24]

Step-by-step explanation:

3x - y = 74

4y = x

Replace x in the first expression by 4y

3x - y = 74 ➡ 3(4y) - y = 74

12y - y = 74

11y = 74

y = 74/11 we can use this to find x

4y = x

4 × 74/11 = x

296/11 = x

Ymorist [56]

Answer:

Number of times she will hit the ball  the next time she plays softball if she is at bat 20 times = 9 times

Step-by-step explanation:

Percentage of times Sierra hit the ball when she was at bat playing softball= 45%

So, we can find:

Number of times she will hit the ball  the next time she plays softball if she is at bat 20 times = \textrm{45\% of 20 times} =0.45\times 20=9\ times

which measurement is closest to the volume of the cone in cubic inches . the height is 7.5 & the radius is 5.62 . show work
Dominik [7]
To find the volume, you would use the formula V=1/3 pi times radius squared times the height. So, you would multiply 1/3 x 3.14 x 5.62^2 x 7.5. This equals approximately 248 cubic inches.
